These are vehicle-year records whose recorded OEM ranges overlap this 2020 Ford Ranger. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 17 donor years. Listed 15 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Center-bore records disagree (target year-level hub 92.3 mm vs trim range 93.1–93.1 mm; donor year-level hub 92.3 mm vs trim range 93.1–93.1 mm). Unqualified overlap is not claimed until the conflict is resolved.
Lug thread is not fully recorded for this comparison. Hardware must match the 2020 Ford Ranger studs and the selected wheel’s seat. Unknown hardware is not a match.
Bolt pattern data is incomplete for a full interchange decision.
Recorded vehicle-side thread for the 2020 Ford Ranger is M12x1.5. This donor year is recorded as 1/2"-20UNF. That is the vehicle stud/nut thread, not an intrinsic thread stamped on the wheel. Hardware must match this vehicle’s studs and the selected wheel’s seat and engagement. Existing hardware may be reusable if it already matches. Seat style is not in this dataset, so products are not a verified fit.

Use this guide to compare wheel and tire measurements for a 2020 Ford Ranger. The specifications below are the supplied OEM fitment data and may not apply to every trim, package, market, or replacement wheel. Always confirm measurements with the vehicle, the owner's manual, the driver's door-jamb label, and a Ford parts source before ordering.
The following values are currently available for comparison:
| Specification | Known value | Important note |
|---|---|---|
| Bolt pattern | 6x139.7 | Six studs on a 139.7 mm pitch circle diameter. |
| Center bore | 93.1 mm | The wheel's center bore must fit the vehicle hub correctly. Hub-centric rings may be relevant only when their dimensions and application are confirmed. |
| Thread size | M12 x 1.5 | Confirm lug nut seat type and thread engagement before installation. |
| Rim diameter | 18 in | May vary by trim or wheel package. |
| Rim width | 8.0 in | Confirm the wheel's stamped width before mounting a tire. |
| Wheel offset | ET55 | Offset changes inner and outer clearance and should be compared with the original wheel. |
| Backspacing | 6.17 in | Check this value against the actual wheel, because backspacing and offset are related but not interchangeable measurements. |
| Tire section width | 255 mm | Actual mounted width can vary by tire model and approved rim width. |
| Tire aspect ratio | 70% | Use the complete tire marking and door-jamb label to confirm the correct tire size. |
| Tire rim diameter | R16 | This conflicts with the supplied 18-inch rim diameter. Verify the intended trim, wheel, and tire before using these values as a matched set. |
The supplied data includes both an 18-inch rim diameter and an R16 tire rim diameter. Those two diameters cannot describe one mounted tire-and-wheel combination. Treat them as separate reference values until confirmed through the vehicle's door label, owner's manual, wheel markings, or a Ford parts source.
Start with the calculator's “Wheels from (donor vehicle)” fields and enter the donor wheel's bolt pattern, center bore, diameter, width, and offset when those fields are available. Then enter the 2020 Ford Ranger in the “Installed on (your vehicle)” fields using the confirmed vehicle measurements.
Use the calculator to compare a donor wheel with the Ranger rather than relying on bolt pattern alone. A matching 6x139.7 pattern does not by itself confirm brake, suspension, fender, center-bore, or load-capacity clearance. Compare the donor wheel's offset and width with the known ET55 and 8.0-inch reference values, but verify those values for the specific trim and wheel.
The calculator also allows a custom wheel size and custom tire size. Enter the proposed rim diameter, rim width, and offset, then enter the tire section width and aspect ratio. When rim diameter changes, the calculator updates the tire diameter in the comparison. Review the resulting diameter, sidewall, and clearance differences before purchase. Because the supplied OEM tire data has an R16 and the supplied rim data has 18 inches, verify the baseline before interpreting the comparison.
Confirm the exact Ranger trim and factory wheel package first. Then compare the donor wheel's stamped specifications with the vehicle's confirmed requirements. Check all of the following:
Do not assume a wheel is safe because it physically bolts on. The wheel must also have suitable load capacity and adequate clearance. If any specification is missing, obtain it from the wheel manufacturer or an OEM source rather than estimating.
Plus sizing generally means changing wheel diameter while selecting a tire with a shorter sidewall to keep overall tire diameter reasonably close to the original. The calculator can show how a custom rim diameter and tire size change diameter and related measurements, but it does not replace a physical clearance inspection or the tire manufacturer's approval.
For a proposed upgrade, compare the original and custom section width, sidewall height, overall diameter, wheel width, and offset. A wider tire or a different offset can reduce clearance even when the overall diameter is similar. A larger wheel may also increase the risk of wheel or tire damage and may affect ride comfort.
There is no single upgrade that can be confirmed for every 2020 Ford Ranger from the partial data provided here. Verify the intended trim, suspension, brake package, wheel load rating, and tire requirements with Ford documentation and the wheel and tire manufacturers.
Inspect each wheel for cracks, bends, corrosion, damaged mounting surfaces, and missing identification markings before installation. Clean the hub and wheel mating surfaces without removing metal. Do not use spacers, adapters, or hub rings unless their dimensions, load rating, and application are specifically confirmed.
Install the correct lug nuts for the wheel's seat design and the vehicle's M12 x 1.5 thread specification. Tighten in a star pattern with a calibrated torque wrench using the torque value specified by Ford or the wheel manufacturer. Do not rely on an impact wrench for final torque.
After installation, check that the wheel rotates freely and that there is clearance to the brake components and suspension. Lower the vehicle, recheck torque after the first drive or according to the wheel maker's instructions, and inspect for contact after steering from lock to lock. Set tire pressure using the vehicle's door-jamb label, not the maximum pressure molded into the tire.
A calibrated torque wrench, suitable socket, tire pressure gauge, tread-depth gauge, and a reliable jack and jack stands are useful for a careful wheel change. Use jack stands on solid, level ground and follow the vehicle's lifting points. A basic automotive torque wrench can help verify final lug nut torque, while a digital tire pressure gauge can help confirm cold inflation pressure.
For professional or repeated work, add a wheel measuring tool, thread and lug-seat identification tools, and manufacturer documentation. Tool availability does not confirm fitment, so measure the wheel and verify specifications before mounting tires.
The supplied reference is 6x139.7. Confirm the exact vehicle and wheel package before ordering, because a bolt pattern alone does not establish complete fitment.
The supplied center-bore reference is 93.1 mm. Compare that dimension with the donor wheel and confirm whether any hub-centric ring is actually required and correctly sized.
The supplied thread specification is M12 x 1.5. The correct lug nut must also match the wheel's seat style and provide proper thread engagement.
The data lists an 18-inch rim diameter but an R16 tire rim diameter. An R16 tire mounts to a 16-inch wheel, so these values should not be treated as one matched set. Check the door-jamb label, owner's manual, wheel markings, and OEM parts information to determine the correct trim-specific combination.
No. The wheel must also have compatible center bore, diameter, width, offset, backspacing, load capacity, lug-seat design, and brake and suspension clearance. Use the calculator for comparison, then verify the result against OEM and manufacturer information.
Yes. Offset changes how far the wheel sits inward or outward relative to the hub. The effect depends on the original and replacement wheel widths as well as offset, so compare both measurements in the calculator and perform a physical clearance check.
Verify the complete tire size, approved rim-width range, load rating, speed rating, overall diameter, tire pressure requirements, and clearance. Use the vehicle label and tire manufacturer data. Do not use the conflicting R16 and 18-inch values together without confirming which specification applies to your Ranger.
An impact wrench may be used cautiously for initial installation, but final tightening should be performed with a calibrated torque wrench using the vehicle or wheel manufacturer's specified torque. Recheck the installation after driving as directed by the manufacturer.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
